Phantom power is a way to provide power to microphones—that need electricity to operate, but that don't have a dedicated AC power source. On the other hand, dynamic mics—the ubiquitous Shure SM57 and SM58 mics, for example—do not require power.
Why do I need phantom power? Phantom power, commonly designated as +48V or P48, was designed to power microphones without using bulky external power supplies such as the ones required for tube microphones. It's most widely used as a power source for condenser microphones, which have active electronics.
USB microphones make everything easier by allowing you to plug straight into your computer, often without even having to deal with drivers or special software of any kind. Even USB condenser mics get their phantom power right from the USB port, so there's no extra power supply needed.
The Auxiliary input is designed for an amplified signal such as what is output from a smartphone headphone output. In order to use a microphone with the Aux input, it would need to be used with a microphone preamplifier before the signal gets to the Livemix Aux in.
No. There is not enough gain to amplify a microphone in a line input. Line Inputs are not designed for microphones and although it is possible to use them, the results will not provide optimum. If you have a mic with a jack plug on it you should change it for a XLR connector.
When a microphone is connected to a computer (via an audio interface or another analog-to-digital converter), it sends/inputs information into the computer. This means microphones are input devices. Digital mics with built-in headphone amps that receive info from computers are input/output devices.
Plug the small end of the cable into the microphone. Plug the other end of the cable into a USB port on your computer. Control the sound by launching your computer's digital audio workstation (DAW). Turn the computer's main output level down and switch the input and outputs to your microphone.
You should be able to test for phantom with a multimeter, plug an XLR cable into the channel input (make sure the trim and channel volumes are down to be safe) check the free end of the cable for power, usually between 12V and 48V. Yes, that's actually the best test.
This is a great
microphone. I use this for producing video training material. It was plug and play with my Windows 7 computer and my windows 10 computer.

XLR cables are used in audio applications ranging from live shows to professional recording sessions. XLR cables have three pins and a circular connector. They are used to deliver balanced microphone and line-level signals over long distances, so an XLR cable can be simply thought of as a microphone cable.
If a single-ended (unbalanced) output device such as a keyboard, consumer tape deck, sound card, or receiver is connected to any balanced preamp, make certain phantom power is turned off on that input. Depending on the design of the device, its output can be permanently damaged if phantom is applied.
If you are running live sound, you probably won't notice much of a difference if you have phantom power switched on for a dynamic mic. However, if there happens to be an imbalance in the amount phantom power voltage being applied to each pin, the power can damage or destroy a dynamic mic.
You will need to consult the owner's manual for your device to determine if it does. On most devices, phantom power can be turned on or off via switch, button or software. You may find this labeled as “+48V” instead of “phantom power.” In order for phantom power to work, a balanced microphone cable must be used.
But if you want to turn off the phantom power and turn down the gain even with an XLR, it won't hurt anything. It might not hurt to just get in the habit of turning gains down, and Phantom power off every time, regardless of connector type, just so you don't forget.
Most audio interfaces that feature mic inputs will also supply phantom power. Because only certain kinds of microphones require phantom power, audio interfaces have a switch to turn it on and off.
1. Less Interfering Noise. Honestly, condenser microphones are great because they pick up everything in crisp, clear detail. Since dynamic mics are typically less sensitive than condenser mics, it's far better at recording just your vocal sounds, rather than everything else in the room or auditorium.
Yes, you do need an audio interface to record music into your computer. The Blue Yeti USB mic you refer to is essentially an audio interface with limited features built into a microphone. Your recording environment will also affect the quality of your recording.
A condenser microphone needs external DC power to operate. Phantom power is DC voltage sent down the microphone cable to power the preamplifier of a condenser mic capsule and/or to provide a polarization charge to the back plate of the element.
Conclusion. The sound contribution of preamps is not so much in its frequency response but in the texture it imparts on the sound. However, a preamp shapes the sound to a much lesser degree than one would think. Usually, its sound character only becomes obvious at high gain settings or when you drive it into distortion
When you're connecting studio monitors (powered speakers) to an audio interface, you plug them into the line-level outputs. You can also use line-level inputs and outputs to connect external effects, compressors, limiters and all kinds of stuff. Other connectors include 3/8" mini and RCA (phono) connectors.
A preamplifier (preamp or "pre") is an electronic amplifier that converts a weak electrical signal into an output signal strong enough to be noise-tolerant and strong enough for further processing, or for sending to a power amplifier and a loudspeaker. Without this, the final signal would be noisy or distorted.
A preamp is a single piece of recording equipment designed to amplify low level signals, while an audio interface is what sends the recordings to a computer, effectively translating real music into digital music.
You can't plug the head/chassis of most tube amps directly into an interface. The power amp needs to see a what's referred to as a reactive or dummy load or you run the risk (almost surely) of blowing your output transformer.
A Preamplifier (preamp) is a device in which the user can connect all audio or audio/video source components (such as CD, DVD, or Blu-ray Disc players). The preamplifier can be used to switch between sources, process audio and/or video, and also supply an audio output signal to what is referred to as a Power Amplifier.
When to use a Pad
- Make sure your preamp does not overdrive your AD-Converters. Turn down the gain control on your preamp.
- If you still hear distortion, make sure your preamp doesn't clip.
- If you're sure neither your converters nor your preamp distorts, engage the pad switch on your microphone.
Plug into a line level output on the channel strip and plug the other end of the cable into the audio interface insert plug. This will provide a direct signal path from the channel strip to the audio interface ADC and bypasses the audio interface preamps completely.
